`ATTJliJGHll/l:ENT FOR, SEWING-TEACHINE TABLES.

` .application filed March 26, 1920. Serial No. 368,919.

To oZZww/nt 'aft may concern Be it known that l, Anenn'r L. lrrrnn now, a citizen ofthe United States, residing at St. Paul, in the county of Ramsey and `Statecf Minnesota, have invented certain new and; useful improvements 1n Attach ments for Sewingll/lachine Tables; and l dohereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the `art j to which it appertalnsto make and use the samep j duit sections giand j My invention vide an attachment for power sewing machine tables, which includes lanip-supports ing brackets, alconduit forelectric light wires, and spool-holding spindles. The

`purpose of the attaehn'ient is to support these various different elements abovevthe table top, so as to leave the table top `clear for the work, and at the same time`,eliininate a large amount vof noise due to vibration.

To the above yend,generally stated, the invention" consists of the novel devices and combinations of `devices hereinafter described and deiinedzin the claims.

In the accompanying drawings, which illustrate theinvention, like characters indicate like parts throughout the several views. l

Referring to the drawings y Fig. 1 is a' perspective viewiof a sectional `double-trough table, having the attachment secured thereto;

l? 2 is a fragmentary perspective view `ofone ofthe conduit sections, with the cover thereof lifted therefrom;

Fi. 3 is a view principally in transverse section taken on the line 3 3 of Fig. 1, on an enlarged scale;y j

ltigeL .'s aperspective view, in transverse section, taken through one of the con- `Figp is a view `in longitudinal central vertical section taken through the connect ed ends of two of the conduit sections.

The numeral 6 indicates a sectional. double-trough sewing machine table having on each side board, fof each section thereof,

a power sewing machine '7. Said table and j of well known standard construction; .j

rlhe improved attachment includes a plus i vrality of `ift-shaped'brackets 3,which straddle the trough in the Vtable 6, and the legs f thereotwrest, upon the side beards of the for its object to pro-v` slots 16 in the sides of said sections.

. table at the'inner longitudinal edges thereof and are rigidly secured thereto by screws.

'The brackets 8 have, in their upper eX- tremities, loops 9, in which is mounted a round rod l0. This rod l() not only-`connects the brackets 8 and holds the same against movement toward and from' each other, but it affords a support for a multiJ plicity of thread guides 11, each of which has two eyes through which the thread from spools, hereinafter referredto, is extended. These thread guides 11 may be adjusted lon` gitudinally on the rod 10, but, if desired, they! may besecurely held to therod by means of staples or other fastening devices. its shown, there is a bracket 8 at the end ofthe table and at each joint, between the sections thereof. A sectional` conduit l2 en tends the full length of the table 6` within the brackets 8, and it will be notedthat there is a section of this conduit for each section of the table. The conduit 12 is in the forin of a channel provided with a removable sec'- tional Vcove-r 13, the longitudinal edges of which extend considerably outward of the sides of the conduit, and on the under side thereof are longitudinally extended grooves 13, in which the upper edge portions ofthe vsides of the conduit extend. j j Each section of the conduit 12"andeach section of the cover 13, is made from a single sheet of metal bent to forni the conduit 152 and the grooves 13', inthe cover 13. The conduit 12 is secured to thebrackets 8 considerably above the table top, by means of stove bolts ldinserted through aligned holes in the sides of said conduit and the legs of the' brackets. The legslof the brackets 3,

are connected by telescoping the one within the other and inserting stove bolts `15 through coincident longitudinally extenrled he adjacent ends ofthe cover sections are connected'by overlappingthe saine and inserte ing a long stove bolt 17 through coincident longitudinally extended slots 18 formed therein and correspondingly formed slots 19 in the bottoms of the conduit sections. rllhe upper and lower edges of the sides of the ends of the conduit sections, which are telescoped into the adjacent conduitl secn tions, are beveled, to permit vertical annular meveinentoit said conduit sections in respect to each other The purpose or' the longitudinal slots 16, 18 and 19 is to compensate ior any irregularities inthe alignment of the table sections or in the varying lengths thereof.

Securedto each cover section is a plurality of upright longitudinally spaced spoolholding spindles 20. 1n Fig. 1, a spool 21 is shown on one ot the spindles 20 and the thread 21, Wound thereon, extended through the eyes in one of the thread guides` 11, and y'from thence, it will be extended to one of the sewing machines. he thread guides 1l not only hold the thread above the table top, where .it is out ot they way,

but act as sort ot tension devices to prevent the thread from unwinding too 'tast trom the spools.

At substantially the longitudinal center of each conduit section, is a double lamp-supporting bracket 22, which is in the 'form ot an inverted vyoke of such-size as to Fit closely against the bottom and sides ot the conduit and is securedzto the bottom thereof by stove bolts 22. The ends of the brackets 22 extend horizontally outward at the top ot the conduit 12 With theprojecting edge portions of the cover 13 resting thereon and are secured thereto by stove boltsv 23.

ceive the curved inner end oi:A a longitudinally contractable and extensible lamp-supporting arm 25 having on its outer end an electric lamp 26 and shade 27. The lampsupporting arms 25 are tubulaiand each comprises telescopically connected members held by a set screw 28 in different longitudinal adjustment.

Main electric light wires 29 are lai'd in the conduit 12 and branch lamp cords 30, tor each lamp 26, are secured thereto. These branch lamp cords 30 are arranged in groups'for the two lamps on each table section, extend through bushings 31 in' the bottom of the conduit 12, and the tubular lamp-supporting arms 25, and are attached tov the lamp terminals. There must, ot course, be sufficient slack in the lamp cords 30, between the bushings 31 and lamp-supporting arms 25, to permit the required longitudinal adjustment of said arms. The curvedinner ends of the lampsupport is, arms 25, by their biting interlocking eng. gement with the brackets 22, hold the lamps 26 in various different adjustments in re` spect to the sewing machines.

From the above description, it is evident that a sewing machine table, equipped with my attachment, which supports the electric light wires, lamp cords, lamps, lamp bra-ckets and. spoolsrabove the table top, leaves the table freer for the work so that the' same canbe easily handled. It also dispenses with .thecustom-ary'Y spool stands, which are In each endet each bracket 22 is a hole 2d to revery noisy, due to vibration. The att-ach ment can be very easilY attached to tables of standard make, and the electric light wires and cords may be placed in the couduit and the necessary connections made bc- 'lore the cover is placed on thc conduit. .ln case it is necessary to make repairs, changes or additions to the electric light wires or cords, the conduit cover may be easily rcmoved to expose the same.
